.4 An article. of furniture, in accordance with this invention, is foruse in connection with school rooms, and with reference to Figures 1 to13 inclusive, comprises a supporting pedestal, a desk having its frontwall constituting a vertically adjustable seat back, a verticallyadjustable supporting element for the desk and which isadjustablymounted in the pedestal, a vertically adjustable seat support slidablyconnected with the pedestal, and a. seat hinged to the seat support.

The supporting element for the desk is independently adjustable withrespect to the seat support, and the latter is independently adjustablewith respect to the adjustable supporting element for the desk. Thefront wall of the desk and which constitutes a seat back is adjustableindependently of the vertically adjustable supporting element, andfurther independently adjustable with respect to the verticaladjustablev seat support. By this arrangement three independentadjustments are had.

The supporting pedestal comprises a base 1 and a stem 2. lVhen thepedestal is employed for supporting the deskand seat, it is fiXedlysecured in position by hold-fast devices 3 extending through the basethereof. Preferably the stem 2 is of tapered contour and the base 1 offlaring configuration and which terminates in and is integral with thestem 2. The pedestal is constructed of any'suitable metallic materialand may be cast or pressed.

The stem 2 is formed with a polygonalshaped socket 4, which extends fromthe upper end of the stem 2 and terminatesat a point in proximity to thepoint of joinder of the stem 2 with the base 1. The stem 2 near its topis provided with a threaded clamping element 2 of the same type as theclamping member 75 to be hereinafter referred to.

The forward face of the stem -2 is.k provided with a pair of'oppositelydisp-osed spaced forwardly projecting Yangle-shaped flanges5, 6, which are thesame in width` from the upper to the lower endthereof and each of said anges in connection with the stem 2 provides apocket 7 and the said pockets are oppositely disposed Vwith respect toeach other. That portion of the forward face of the stem 2, which isarranged between the flanges 5 and 6, is plane throughout, as at 8, andcentrally of the plane face of the stem 2 there is arranged a series ofsuitably spaced superposed sockets 9.

The forward face of the stem 2, in proximity to its lower end, isprovided with an o'set portion 10, having a flat top 11 and formedintegral with the offset portion 10 is the lower termini of the flanges5 and 6. The outer forward corner of each of the iianges 5 and 6 isrounded, as at 12.

The stem 2, nea-r its upperI end, is formed with a laterally disposedopening 18, which communicates with 'the socket 4, and shiftably mountedin the opening 13 isa locking member 14, Vhaving a bevelled inner end15. rlhe locking member `14 extends into the socket 4 and furtherprojects outwardly with respect to the stem 2 and is lixedly secured, asat 16, to resilient support 17, secured at its lower end, as at 18,against the outer'face of the stem 2. The upper end of the support 17 isoffset, as at 19, to provide a finger hold or grip. The support 17 1normally retains the locking member 14 in the position shown in Figures1 and 2, that is to say, extended into the socket Y 4 so as to bepositioned in the path of the vertically adjustable supporting elementsfor the desk, to be hereinafter referred to, and said locking member 14provides means for releasably securing the element in the position towhich it has been adjusted. When the locking member 14 is movedoutwardly, such movement is had against the action of the resilientsupporting element 17, as the latter always tends to maintain thelocking member 14 in its inward position, as shown in Figures 1 and 2.

rThe desk includes a U-shaped body portion, preferably constructed fromthin sheet metal, which is bent to provideva desk bottom 20, a pair ofside walls 21, 22, an outwardly projecting right angularly disposedfia-nge 23 at the top of each wall 21 and aV lil posed flange 2e at thefront end ot the bottom 20. The material torn'iingthe side walls and 22is bent to provide a reinforcing flange 25 at the rear end of each ofthe walls 2l and 22. Each of the 'flanges 23 is provided with a seriesot openings 26 and the bottom 20 in proximity to the flange 24 hastoi-med therein a pair of openings 27 and further provided rearwardly otthe openings 2l" with a pair ci openings 2T.

rihe desk further includes a top 28, preterably constructed from woodand of one piece7 although the top 28 can be formed of any suitablematerial, and said top 28 projects rearwardly fi nn the walls 2l and 22and slightly forward with respect to the forward ends of said walls 2land 22. The top 28 is ot' lgreater width than the width of the bodyportion of the deslr and said top 28 is secured in position by hold-tastdevices 29 extending up through the 'openings 26 and engaging in saidtop 28.

'llhe desir 'further includes an adjustable iront wall7 whichfurthermore constitutes a seat back and said front wall is indicated at8O and is of substantial height tor the purpose for which it is intendedand preterably ot materially greater height than the height 1t' the bodyportion oiC the desir, so that the trout wall 8O will extend above thetop 28 and below the flange i-"is shown7 the front wall 30 is formed ota plurality ot' sections suitably secured 'together and with each o'lthe sections Vtermed ot wood, but it is obvious that the iront wall canbe set up from a single piece ot material and that the material can beother than wood. Preferably the forward face of the front wall 30 otEcompound curvature and the rear tace pla-in7 but it is obvious that the`front tace can be of any curvature desired to atlord comfort to thepupil when leaning; against the scat bach.

'ihc front wall 30 is vertically adjustable relative to the body portionof Jthe desli and Yfor such purpose a pair oi' adjustable ng' devices isprovided and which notonly pei-tl Y the function ot connecting' theiront wall with the body portion the desir, but also provide meanswherebiv the iront wall can be vertically adjusted with respect to saidbody portion. As each ot the coupling-g` ceviees is ot the. sameconstructiond but one will be described? as the scription oi one willapply to the other.

Each of coupling' devices consists ot an anale-shaped member otsubstantial length comprising" a 'forward arm 3l and a rear arm and withtho former disposed at right angles with respect to the hitter7 andprit-ject i; inwardly thereifroin The torward arm 8l is provided with aseries of oneuiix's 3S near its `tree side edge and turnier providedwith a row of superposed Y, minates at a point in proximity to the lowerend ther-ectk iflach'coupli vrther include.; a suspension bar Elthickness 'l which. iii-.dicaI he bar 86 is p tioned against lace of a wor 22 at the torward end thereof.; an

tixedly secured therewith by he leid-tast devices engaging in theopenings in thel side wall, and also in the 3S) in the bar ljreiierablythe devices 3? are` count rsunk in 'th The forward sid-e edge ot the bar38 has es; tending therefrom a set oi" spaced polyonal-shaped teeth d()vwhich engage into a series oil openings o'f the row ot openings formaintaining;` the angle-shaped niember in the position to which it hasbeen vertically adjusted with respect to the body portion oi the desk.

For the purpose tiXedly securing the angle-shaped member of the couplingdevice in the position to which it has been vertie cally adjustedremovable retainine niembers are provided, shown two in numherj and eachoit which is indicated at di. llach reta'siingY member comprises athreaded shank ha *ingr its outer end Yformed with an enlarged head l2ilach of the shanlts Lil ot a retaining member extends through the slotsand has threaded with the wall of an openingY ot the plurality oicopenings i8 provided in the bar 8G. linterposed between the head e2 oitretaining` member and the outer 'tace of the bar d@Il is a washer dd.Although but two retaining' members are shown in. connection with eachcoupling devicea yet it is obvious that the number thereot can beincreased it desired. The retainingmembers iixedl. secure theangle-shaped members to the bars E@ due to the threaded engaa'ement oithe retaining` members with the par in connection with the heads t2bearing` against the washers le, which abut against the outer face otthe bar 86. The slot in the arm 32 permits of the shittingr o ananfleshaped member ot a coupling' device vertically when the retainingmembers are moved from clamping' position and by this arrangement itnecessitate the entire removal of the i 'gigi member when it is desiredto shift ann'leshaped member.

he front wall is arranged against the arms and project outwardl. in alateral direction with respect there o., and said v front wall 80 issecured to the arms 3l b "jh the 1 i N dll hold-fast devices e5extending throu openings 83 and engaging in the fro;

30 from the rear thereof, and whereby the angle-shaped members of thecoupling devices are permanently connected to the front. wall 30.

The vertically adjustable supporting element for the desk comprises acombined supporting and coupling bracket and a headed verticallyadjustable standard. The bracket consists of a hollow rectangular bodyportion 46, closed at its top and open at its bottom and disposedtransversely with respect to the bottom 2O of the body portion of thedesk and which provides a rectangular' socket 47. The top of the bodyportion is formed with a pair of openings 48 which register with theopenings 27. The front, well as the rear wall of the socket 47, isformed with a pair of spaced openings 49. Formed integral with each endof the body portion 46 and extending rearwardly therefrom is a pair ofoppositely disposed angle-shaped arms 50,51, each having 'a verticallydisposed portion and a horizontally disposed portion projecting inwardlyfrom the top of the vertical portion and formed with an opening 52. Thehorizontal portions of the arms 50,751, are connected together by abrace member 58. rThe openings 52 register with the openings 27, andextending therethrough are hold-fast devices 54 for connecting said arms50, 51 to the bottom 20 of the body portion of the desk. The verticallyadjustable standard is indicated at 55, is of substantial length andconforms in contour to the shape of the socket 4 and said standard 55 ispositioned and vertically adjustable in the socket 4 and further has asnug sliding fit with the walls of said socket 4. The standard 55, atits upper end, is formed with a head 56 which projects at right anglesthereto and in opposite directions, and said head 56 is of a lengthsubstantially equal to the length of the socket 47. The head 56gradually decreases in height from a point removed from each side of thestandard 55 to each end of the head. The length and width of the head56, are such as to provide a snug lit therebetween and the walls of thesocket 47. The head 56 is secured to the front and rear walls of thesocket 47 by hold-fast devices 57 which extend through openings 49 insaid walls, and also through the head 56 at 'each side of the standard55. rlihe body portion 46 and head 56 may be set up as a single unit ifdesired.

rllhe rectangular body portion 46 of the combined supporting andcoupling bracket is secured to the bottom 20 of the body portion of thedesk by the hold-fast devices 58 which extend through the registeringopenings 27 and 48, and said hold-fast devices further extend throughthe head 56 near each end thereof, so that the head 56, body portion 46and bottom 20 will be fixedly secured together'.

rThe rear face of the standard 55, is formed with a row of superposedsockets 59, each having a bevelled lower wall 60. The locking member 14carried by the standard 2, engages in any one of the sockets 59 for thepurposeof maintaining the standard 55 in the position to which it hasbeen adjusted. The locking member 14 prevents the downward movement ofthe standard 55, but owing to the sockets having the bevelled lowerwalls 60, the locking member 14 does not interfere with an upward shiftof the standard 55 when desired, and this is due to the fact that as thestandard moves-upwardly the bevelled end of the locking member 14 willshift off of the bevelled wall 60 against the action of the resilientsupport 17. 1

The manner of setting up the vertically adjustable supporting elementfor the desk with respect to the latter and also with respect to thepedestal permits o-f the vertical adjustment of the desk to the desiredheight and further that such vertical adjustment is had independent ofthe manner of adjusting the front wall 30 relative to the Vdesk body.

The vertically adjustable seat support, which is slidably connected withthe stem 2, consists of a rectangular bar 61 of substantial length,width and thickness and which terminates at each end in a curvedforwardly extending arm, as indicated at 62, 68. Each of the arms has anupstanding portion at its free or forward end, as indicated at 64. Thebar 61 on its rear face is provided with a pair of angle-shaped sockets65, 66, and with the outer side wall of each of the sockets aredslightly and further curved to conform to the curvature of the forwardouter corners of the flanges 5 and 6. The bar 61 is slidably mounted onthe flanges 5 and 6 for the purpose of connecting the seat support tothe stem 2. The bar 61 is mounted on the flanges 5 and 6 from the topthereof. The bar 61 has its rear face further provided with a recess 67and communicating with the bottom of said recess is an opening 68 whichextends from the front side of the bar 61. The opening 68 is ofmaterially less diameter than the diameter of the recess 67. through theopening 68, as well as through the recess 67 and further having areduced rear terminal portion 69, is a spring controlled locking member70 having its outer end formed with a head71, which abuts against theouter Side of the bar 61. The locking member 70 is provided with a lug 72 and interposed between the latter and the bottom of the recess 67, aswell as surrounding the locking member 70, is a coiled spring 73, whichnormally maintains the head 71 Extending against the outer tace of thebar 6l and further maintains trie reduced inner terminal 69 of thelocking member 70 in one ot the sockets 9. yllhe locking member 70 inconnection with a socket 9 maintains the seat support in the position towhich it has been adjusted.

F or the purpose oit clamping the seat support in its adjusted position,the bar 6l below the recess 67 is provided with a transversely extendingopening 74, formed with a threaded wall, and threadably engaging withsaid wall is a peripherally threaded clamping member 75 provided with apolygonal-shaped bore 76 from end to end thereof. The clamping member 75is ot a length greater than the thickness ot' `the bar 6l and projectsforwardly therefrom. The clamping member 75, after the seat has beenadjusted, is forced inwardly against the tia-t iace S of the stem 2 andwhich sets up a. clamping action and 'forces the walls ot' the sockets65 and 66 to bind against the tianges 5 and 6, whereby the seat supportis tixedly secured in its adjusted position.

)is illustrated in dotted lines in Figure a tool or other implement 77is shown in connection with the clamping` member 75, for the purpose ofshifting it to or from clamping position, and the tool has apolygonal-shaped end vtor engagement with the wall ot thepolygonal-shaped bore 76, so that when the tool is revolved theclamping` member 75 will be carried therewith. litbthe tool is revolvedin a clockwise direction the member 75 will be shifted to clamping`position and it revolved in an anticlocltwisc direction the member 75will be withdrawn t'roin clamping position.

rllhe hinged seat consists of a body portion 76 oi anj7 suitablematerial and with its upper tace curved in any desired manner andturther set up ot the desired width and length and is carried by a pairoic spaced tapered supporting` members 79 and 66. Each ot the members79, 86 is formed at its top with an outwardly extending flange Sl.through which extends hold-fast devices 82 for tiXedly securing the bodyp0rtion 76 to the supporting members 80.

The outer taceT at the rear end of a supporting member 79 or 80, isformed with a circular pocket 62, and each of said members at its rearend :is provided with an opening 83 which communicates with the pocket82. The inner tace ot the upstanding portion ot either of the arms 62 or63. is Jformed with a circular enlargement Se, which corresponds to thediameter ot' a pocket 82 and is seated therein, and each ot' theenlargements 84 has a snug sliding tit with the wall or" the pocket 62.The upstanding end 6st of an arm 62 or 63 is vprovided with an opening85 which registers with an opening 63. 4lelow the enlargement 64, theupstanding portion 64 is provided with a pair of oppositely eX- tendinginclined shoulders 86, 87, against which rides the curved lower rearcorner 88 oit a supporting member 79 or 80. EX- tending through theregistering openings 63 and 65 is a headed bolt 89, provided on itsinner end with a securing nut 90. The bolts 89 provide` means iorconnecting the members 79 and 60 to the upstanding end 6ft of the arms62 and 63. `When the members 79 and 8O are connected to the upstandingends 6e or the arms 62 and 68, the flanges 8l ot the members 79 and 80overlap the top of the upstanding end 64;. Mounted on each bolt 89, aswell as depending therefrom, is a strap 91, which has its lower endconnected by a hold-fast device 92 to an arm 62 or 63. The strap 91, atits upper end, is interposed between the member' 79 or 6() and a nut 90.

The providing of the circular enlargements Se on the upstanding ends 64of the arms 62 and 63 and the seating of said circular enlargements Selin the pockets 82, overcomes the. ridingof the supporting members 79 and8O upon the bolts 69, as when the seat is shifted the walls of thepockets 62 will ride against the enlargements 84 and which constitutethe pivot of the hinge. rllhe shoulders 66 and 87 overcome the necessityot employing lugs, as stops, when the seat is swung to t'ront positionor to rear position and when swung to front position the lower edge otthe meinbers '79 and S0 seat on the shoulders 66, and when swung to rearposition the rear edge ot the members 79 and 60 seats on the shoulders87. The rounded inner lower corners of the members 8() and 81 provide aclearance with respect to the shoulders 86 and 87, when the seat isshifted to its lowered or forward position or to its rearor upstandingposition.

1With respect to the construction shown in Figures lf-l and l5, relatingto what may be termed a rear seat, the construction differs only withrespect to the. vertically adjustable standard mounted in the pedestal.In the application of the invention for the purpose of setting up a rearseat, the pedestal, which is indicated bythe reference character 99, theadjustable seat support indicated at 94:, and the seat indicated at 95and its hinged connection, are the same in construction as that referredvto in connection with Figures l to 13, and, theretore, it is thoughtunnecessary to specifically describe the said elements,

The standard indicated at 96 corresponds in construction to the standard55, with the exception that the head 97 ot the standard izo 96 isdifferently arranged from that of the head 56 of the standard 55. Thehead 97 is disposed at an inclination and is formed with a rearwardlyextending and downwardly inclined shank 98, which terminates in theupper end of the standard 96. The head 97 is projected forwardly withrespect to the standard 96 and is disposed at an inclination and has thelower portion there- 0f opposing the upper terminal portion of thestandard 96. Secured lto the head 97 by the hold-fast devices 99 is aninverted yoke-shaped supporting bracket 100, having the lower terminalof each arm 101 thereof extending forwardly at an angle, as at 102,providing a support.- The bracket 100, centrally thereof, has anupstanding arm 102. When the head 97 is secured to the bracket 100 it isarranged centrally of said bracket and is further positioned against therear face of the arm 102. The bracket 100 has openings 103 for thepassage of hold-fast devices 104 to se^ure the seat-back 105 to thebracket 100, and said seat back is formed from the front wall of thedesk. The standard 96 has sockets 106 of the same contour as the sockets59 for the reception of the locking member 14. The standard 96 andbracket 100 may be casted or pressed in a unit.

The arrangement shown in Figures 14 and 15 provides for what may betermed a rear seat and with the seat back independently adjustable withrespect to the seat and with the latter independently adjustable withrcspect to the seat back. The adjustments in both instances arevertical. An article of furniture, such as a combined desk and seat, setup in the manner as illustrated and described permits of the desk beingadjusted to the desired height by releasing' the locking member 14 fromengagement with the standard. and further permits of the seat to beadjusted to the desired height by releasing` the retaining member andclamping member, and also permits of the vertically adjusting of theseat back to the desired position, and with. the adjustment of the seatback independent cf the adjustment for the seat, and the adjustment ofthe desk independent of the adjustment of the seat back and the seat.

By setting up the article of furniture from one set 0f castings, andowing to the independent adjustability of the desk, seat back and seat,-the same construction of article may be used throughout the school.from the first grade through the high school, and which is possible, dueto the independent adjustment referred to.

By setting up the device from one set of castings and through theomission or removal or insertion ofrcertain parts, the followingconstructions are provided, a regular seat, a front seat and a rearseat, so, therefore, it is not necessary to make a special front or aspecial rear or a special regular, as an article of school furnitureconstructed in accordance with this invention embodies t-he threefeatures referred to. By way of example, in the article of furnitureas'described, if the desk is removed and the bracket 100 with the seatback secured thereto is mounted in the pedestal., then the rear seat isset up. If a regular is wanted, the bracket 100 is removed and the deskinserted. If a front seat is wanted, the seat supporting bracket isremoved and the front seat is ready. Inversely when a regular is wanted,the seat supporting bracket is again supporte-d in position and thestructure is complete. Therefore, an

article of furniture for school rooms is set up possessing theadvantage` of interchangeability.

It is thought that` the many advantages of an article of furniture,Vsuch as a combined desk and seat, or a seat for school rooms or otherpurposes, constructed in accordance withthis invention, can be readilyunderstood, and although the preferred embodiment of the invention is asdescribed and illustrated, yet it is to be understood that changes inthe details of construction can be had which will fall within the scopeof the invention as claimed.
